Why can't I save very small numbers in a vector?

Hello!

My code is getting points like 5e-9 and i am putting these points on a vector. However after i run it i get a vector full of zeros.

Is there anyway to keep the real numbers in the vector.

Thank you

a=1e-9
fprintf('%.10f',a)

The small numbers are there, but not displayed. (My guess.) Try

    >> format long
    >> a = [1e9,1e-9]
    a =
       1.0e+09 *
       1.000000000000000   0.000000000000000
    >> a(2)
    ans =
         1.000000000000000e-09
    >>
